You just tell them you fought the good fight...and why you fought it......that they will understand.

As for the mess the GOP and Romney/Santorum made of this race....well that will go into various books with various authors giving their take on the matter. None of which will likely be the truth.

Then someday when these thugs are old geezers...they'll play a “Deep Throat” confession to set the record straight....but by then nobody will care....we'll have become a nation unrecognizable to the founders.
